Specification of Letters Patent.

T 0 all whom it may concern:

Be it known that I, GEORGE H. BROOKS. a citizen ofUnited States,residing at 7 48 East Market street, Louisville, in the county ofJefferson, State of Kentucky, have invented a certain new and usefulImprovement in Restoring Attachments to Trolley-l/Vheels and ElectricSignal for the Same, which improvement is fully set forth in thefollowing specification and accompanying drawings.

Referring to accompanying drawings, wherein like reference-lettersindicate like partsFigure 1, is a side elevation of trolley wheel withcatch wheel projection attachments, Fig. 2, is a rear view of the same,Fig. 3, is a top plan view of same, Fig. 4;, is a side view showingcollar with sides extended near the trolley wheel, Fig. 5, is a frontview of same, Fig. 6, is a view showing a section of a car with trolleywheel and pole with attachments and insulated wires leading to batteryand bell or red light signal for notifying attendant of displacement.

In the drawings, WV, indicates the line wire, A, the trolley wheel, B,the trolley pole, O, the catch wheel, D, the journals of catch wheel, Dperforations for journals, E, E, arms, F, the collar, F bolt forsecuring collar and sear spring, G, bolt for supporting and pivotingarms, G perforations for G, H, sear spring for holding arms E, E, out ofcontact with push button I. I is a hard rubber collar. I, is electricpush button, J, is rope for attaching to lower ends of arms E, E, K, K,insulated wires connected with button, battery and bell on car, L,perforation for rope. M, bell or ruby light, N, battery, O, the car.

The catch wheel C, is made preferably solid of brass or suitablematerial, and tapered from the ends towards the center forming a roove,and journals D, D, turned on ends. Said catch wheel'O, is revoluble onits own journals D, D, in perforations D, the arms E, E, are made ofsteel or suitable material, and are inclined inwardly, and downwardlyand are pivoted on short bolts G, said bolts G, are fitted with cotterpins in the end for securing the arms E, E, to the collar F, the saidarms E, E, are provided with perforations at D, D G, G, and L, L, whererope J, is attached. The collar F, is for attaching to trolley pole B,and supports the arms, E, E, the bolt G, and sear v spri ng H, and boltF The scar spring H, holds lower end of arm E, E, out of contact withthe electric push button I, and said push button I, is mounted onnonconducting or hard rubber collar P, for attaching to trolley pole B,opposite lower end of arms E, E. The wires K, K, being insulated andconnected push button I, and leading down trolley pole B, to battery N,and bell or ruby light M. That when the trolley wheel A, is displacedthe wire 1V, is caught by catch wheel 0, which causes lower end of E, E,to press button I, forming electric circuit causing bell M, to ring orred light to flash up thus notifying attendant of displacing of trolleycontact wheel A, so that by a slight pull of rope J, the trolley wheelA, is lowered and catch wheel C, holding the wire IV, is raised abovetrolley wheel A, when said wire WV, slides down inclined side of groovedcatch wheel O, thus being centrally located above trolley wheel A, therope J, is released and the wire IN, is naturally caught and contactrestored. The said catch wheel C, falls to its natural position belowwire WV, remaining out of contact, substantially as described.

Fig. 4, shows a variation with arms E, E, shortened and inclined upwardat the center, and is pivotal at G, on collar F, said collar has sidesextended upwards bringing said arms E, E, nearer the trolley wheel A,and is otherwise the same as Fig. 1, substantially as described.

Having thus described my invention what I claim as new, and desire tosecure by Letters Patent, is-

1. A trolley finder and replacer for electric cars, comprising abell-crank fulcrumed on the rear side of the trolley-pole below theharp, its upper member bifurcated to receive a wheel and its lowermember provided with means for attaching a manipulating line, arelatively long, grooved finder and replacerroller mounted in the uppermember of said bell-crank and ositioned to the rear of thetrolley-wheel, a 1 so arranged that when the manipulating line is drawndownward and backward, the lower member of the bellcrank is drawnbackward, thus elevating the replacer-roller mounted in the upper memberof the bell-crank to a higher plane than that of the trolley-wheel, sothat when the trolleypole is allowed to rise to replace the trolleyWheel the replacer-roller first contacts with the line wire and guidesthe trolley-wheel to such'position vertically under the line wire thatwhen further released it straddles the wire.

2. A trolley finder and replacer, com rising a bell-crank fulcrumed onthe tro leypole below the journals of the trolley wheel, a fork in theupper-member of said bell crank, a relatively long finder andreplacerwheel mounted in said fork, and annunciator circuit, means forclosing said annunciator circuit by pressure of said bell-crank,yielding means for normally holding said bellcrank out of contact withsaid annunciatorclosing means, provision for attaching amanipulating-line to the lower member of said bell-crank, all soarranged that when the trolley-wheel leaves the trolley-wire the findercontacts therewith, isnpressed downward thereby causing the bell-crankto close the annunciator circuit and notify the attendant, and when theoperating line is drawn downward the trolley-wheel is lowered and guidedby the replacer-roller, so thatwhen released it finds its placeautomatically on the wire.

In testimony that I claim the foregoing, I have hereunto set my handthis 31st day of May 1907 GEORGE H. BROOKS. Witnesses:
